The thermophilic fungusTalaromyces emersonii CBS 814.70 produces a thermostable extracellular chitinolytic system when cultured on chitin containing media. The chitinolytic system consists of chitinase (EC 184.108.40.206) and N-acetylglucosaminidase (EC 220.127.116.11). Using fluorescent substrate analogues, in zymogram staining of polyacrylamide gradient and isoelectric focusing gels on which the chitinase system was electrophoresed and focused, respectively, it was found that a number of bands could be resolved. Using isoelectric focusing it was observed that at least 4 extracellular forms of chitinase activity are produced.
